Climbing miniature rose plant named ‘WEKwoagorol’

ABSTRACT

A new variety of Climbing Miniature rose suitable for garden decoration, having flowers of orange and yellow bicolor coloration.

Classification: The present invention relates to a new Rosa hybrida plant.

Variety denomination: The new plant has the varietal denomination ‘WEKwoagorol’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Climbing Miniature Rose. It has a non-disseminated seedling of my creation as its seed parent with the following genetic origin (Work of Art×Goldmarie) and as its pollen parent the variety known as ‘WEKtorroc’ (not patented).

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from other presently available and commercial rose cultivars known to the inventor are the following combinations of characteristics: its excellent color stability throughout the life of the flower, its unusual orange and yellow bicolor flower coloration and its many hairs on the peduncle and flower receptacle. The plant has a spreading climbing growing habit, suitable for outdoor garden decoration.

Asexual reproduction of the new variety by budding as performed in Kern County and Pomona, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘WEKwoagorol’ may be asexually propagated by cuttings, budding and grafting. The budding and grafting successfully occurred on the plant/rootstock Rosa hybrida cv. Dr. Huey (not patented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, a non-disseminated seedling of my creation by the following combination of characteristics: whereas ‘WEKwoagorol’ bears medium sized flowers (about 4.8 to about 7.3 cm. in diameter) of orange and yellow bicolor coloration, the non-disseminated seedling bears significantly smaller flowers (about 3.6 to about 4.2 cm. in diameter) of yellow with light pink blush coloration. The new variety bears double flowers (about 20 to 30 petals), whereas the seed parent bears double flowers with significantly lesser petalage (about 10 to 15 petals).

The new variety may be distinguished from its pollen parent, ‘WEKtorroc’ by the following combination of characteristics: whereas ‘WEKwoagorol’ bears medium sized flowers (about 4.8 to about 7.3 cm. in diameter) of orange and yellow bicolor coloration, ‘WEKtorroc’ bears significantly larger flowers (about 8.5 to about 10.2 cm. in diameter) of deep pink with white stripes coloration. The new variety is classified as a climbing miniature rose with a spreading climbing growing habit with canes about 150 to about 250 cm. in length, whereas the pollen parent is classified as a climbing rose with a significantly taller and wider growing habit with canes about 305 to about 365 cm. in length.

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The new variety may be distinguished from its closest commercially available cultivar, ‘MORart’ (U.S. Plant Pat. No. 7,617) by the following combination of characteristics: whereas ‘WEKwoagorol’ bears medium sized flowers (about 4.8 to about 7.3 cm. in diameter) of orange and yellow bicolor coloration, ‘MORart’ bears significantly smaller flowers (about 4.0 to about 5.0 cm. in diameter) of blending orange and yellow coloration. The new variety bears double flowers (about 20 to 30 petals), whereas the closest commercially available cultivar bears flowers with heavier petalage (average about 35 petals).

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows the flowering thereof from bud to full bloom depicted in color as nearly correct as it is possible to make in a color illustration of the character. The branches used for the photograph came from 3 to 4 year-old rose plants of the new variety grown outdoors in Wasco, Calif. in the month of November. Throughout this specification, color references and/or values are based upon the Colour Chart of The Royal Horticultural Society (1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the new variety grown outdoors in Wasco, Calif. in the month of November. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.

FLOWER

The new variety usually bears its flowers in clusters of three to seven per stem. Flowers are borne in regular rounded to somewhat pyramidal clusters on strong medium to long stems (about 32 to about 125 cm.). Outdoors, the plant blooms abundantly and nearly continuously during the growing season. The flowers have a moderate tea to slightly fruity fragrance.

BUD

The peduncle is about 2.3 to about 3.7 cm. in length, of slender caliper (about 0.2 to about 0.3 cm. in diameter) and usually erect. It is moderately smooth, with few stipitate glands and many hairs. Peduncle color is between 146C and 146A often heavily suffused, especially on the side exposed to the sun, with between 187B and 187A.

Before the calyx breaks, the bud is about 1.0 to about 1.4 cm. in diameter at the widest point, about 1.4 to about 1.7 cm. in length, and pointed to somewhat ovoid in shape. The surface of the bud bears between 7 to 9 foliaceous appendages, few stipitate glands and some hairs, usually with slender entire foliaceous parts extending beyond the tip of the bud about ½ or more of its length. Bud color is between 137C and 137B often heavily suffused, especially on the side exposed to the sun, with between 187B and 187A.

The sepals are about 1.8 to about 2.5 cm. in length and about 0.7 to about 1.0 cm. in width at the widest point. The outer surface color of the sepal is between 137C and 137B often heavily suffused, especially on the side exposed to the sun, with between 187B and 187A. The outer surface of the sepal is smooth and bears between 0 to 4 foliaceous appendages with few stipitate glands and some hairs. The inner surface color of the sepal is near 146C broadly bordered by near 137A. After the sepals open, the inner surface color is often heavily suffused, especially on the area exposed to the sun, with between 187A and 187B. The inner surface of the sepal is covered with fine wooly tomentum; sepal margins are lined with some stipitate glands and hairs.

The receptacle of the flower is of medium length (about 0.4 to about 0.6 cm.) and somewhat thin to average in caliper (about 0.5 to about 0.8 cm. in diameter). The receptacle is urn-shaped in form. Its surface is smooth with many hairs and very few stipitate glands with somewhat thin fleshy walls. The receptacle color is between 144A and 137B often heavily suffused, especially on the side exposed to the sun, with between 187B and 187A.

As the petals open (after the calyx breaks), the bud is about 1.2 to about 1.9 cm. in diameter at the widest point, about 1.4 to about 1.9 cm. in length, and moderately ovoid to somewhat globular in form. The color of the under surfaces of the newly opened petals is between 45B and 46B often moderately suffused with between 53A and 187B. At the point where the petal attaches, there is a large zone of between 2B and 1A. The color of the upper surfaces of the newly opened petals is between 26C and 23C sometimes moderately suffused with between 187B and 53A. At the point where the petal attaches, there is a large zone of between 3C and 4B.

BLOOM

When fully open, the bloom ranges from about 4.8 to about 7.3 cm. in diameter. Petalage is double with about 20 to 30 petals and about 5 to 17 petaloids irregularly arranged. When partially open, the bloom form is moderately globular, slightly high centered to cupped and the petals are moderately tightly spiraled to somewhat cupped with petal edges somewhat reflexed outward. When fully open, the bloom form is more cupped and the petals are loosely cupped to slightly undulated with petal edges moderately reflexed outward.

PETALS

The substance of the petals is moderately heavy and of medium thickness, with upper surfaces moderately satiny and under surfaces matte. The petals are about 1.5 to about 2.9 cm. in length and about 1.0 to about 2.9 cm. in width at the widest point. Petal margins are entire.

The outer petals are moderately obovate to somewhat rounded in shape with rounded to sometimes mucronate apices.

The inner petals are obovate to somewhat oblanceolate in shape with rounded to sometimes mucronate apices.

Petaloids are about 0.7 to about 2.4 cm. in length and about 0.3 to about 1.6 cm. in width at the widest point. Petaloids are irregularly shaped moderately oblanceolate to somewhat subulate with rounded apices.
